oh, I will :) I many years ago I upgraded my Palm Pilot to 8MB
and did some other practice - so soldering flash will be not easy,
but not inpossible. It's possible to train with the usb flash device.

Why hacking? Because it is possible and it is fun :))

Right, me too. But Seans statment that we shouldn't do expect to much
transfer speed from/to microSD gives anouther reason than "just for
fun".
And in every town is some specialist which will be able to solder you
this flash perfectly - in case for people with no experiances, to much
respect or in case that they overestimate their skills and got into
trouble while soldering - as long you do not swith on the power,
nothing (beside of the warranty) is lost.
But the important point in which model/Package Type of the flash will
be used for the Neo1973 - and I speculated that it will be
SLC(Small Block) and maybe even FBGA.
And I guess that USB flash memory devices did not use SLC(Small Block)
- or maybe this will be in *very* small devices ;)

I should use BGA (Ball Grid Array) and should avoid using abbrevations.
So I know that there are some (private) hardware hackers working even
with BGAs - but when the flash is soldered as BGA it is unpossible for
most of us.
Sorry for the confusion,
